File: 218267 <br /> November 30, 2018 <br /> Proposed Construction <br /> We understand that the current development for the site proposes the demolition of the existing <br /> residence, and the subsequent construction of a new single-family residence and associated <br /> improvements. The residence is to include a partial basement. The house is to be of conventional, <br /> wood-framed construction with concrete walls for the basement. New foundation loads are expected <br /> to be typical for this type of structure (i.e. light). <br /> Excavation work at the site is expected to include: crawlspace, foundation,and basement excavations <br /> up to about 12 feet deep. No significant fill placement is anticipated as part of this work. Cuts up to <br /> 12 feet tall for the basement are anticipated as part of the site development. Basement retaining walls <br /> up to 10 feet tall will be required for the proposed construction. <br /> INVESTIGATION <br /> Scope and Purpose <br /> The purpose of our investigation was to determine the nature of the subsurface soil conditions so that <br /> we could provide geotechnical recommendations for the construction of the proposed new residence <br /> and associated improvements. In order to achieve this purpose, we have performed the following <br /> scope of work: <br /> 1 - visited the property to observe the geotechnical setting of the area to be developed; <br /> 2 - reviewed relevant published geotechnical maps; <br /> 3 - drilled four borings near the location of the proposed improvements; <br /> 4 - performed laboratory testing on collected soil samples; <br /> S - assessed the collected information and prepared this report. <br /> The findings of these work items are discussed in the following sections of this report. <br /> Site Observations <br /> We visited the site on November 8, 2018 to observe the geotechnically relevant site conditions. <br /> During our visit, we noted the following conditions: <br /> A - The existing house appears to be supported by a perimeter concrete footing with isolated <br /> interior wooden posts resting on concrete pedestals. The foundation system appeared to be in <br /> good condition, with no major cracks (as observed from the exterior). <br /> 2 <br />
